A phase II trial evaluating capecitabine and irinotecan as second line treatment in patients with oesophago-gastric cancer who have progressed on, or within 3 months of platinum-based chemotherapy

Abstract

Rationale: There is no standard second line therapy for relapsed oesophago-gastric (O-G) cancer.

Methods: We recruited 29 eligible patients with relapsed O-G cancer who had progressed during or within 3 months of prior chemotherapy to assess the efficacy and toxicity of capecitabine [2,000 mg/(m(2) day) on days 1-14] and irinotecan (250 mg/m(2)) given every 3 weeks.

Results: Five patients (17%) demonstrated objective response, while a further seven patients (24%) achieved disease stabilisation. Median progression-free survival and overall survival were 3.1 months (95% CI = 2.2-4.1 months) and 6.5 months (95%CI = 6-7.1 months), respectively. Among symptomatic patients, palliation of tumour-related symptoms included resolution of reflux (5/12 pts), dysphagia (3/9 pts) and weight loss (4/9 pts), improvements in anorexia (4/10 pts), nausea (3/4 pts), vomiting (4/6 pts) and pain (4/16 pts). Grade 3-4 toxicities were diarrhoea (15%), nausea and vomiting (7%), lethargy (31%), neutropenia (31%), anemia (14%) and thrombocytopenia (7%).

Conclusions: Capecitabine and irinotecan has anti-tumour activity as second line treatment for relapsed O-G cancer, and provides an important improvement in disease related symptoms.
